MSI 7870 Hawk Edition has apparently already been released and is a good steal considering it's only $10 more than the r7870 twin frozrIII ($30 with the discounted coupon MSI is promoting, not sure if it applies to the Hawk Edition) while getting twice the performance and even better overclocking! From what i've read on the reviews before this card was released was that the performance of the card rated against even MSI's own 7970's though the 7970 would still fair a bit better during overclocks and performance!

Wish I had waited out for this card... . Anybody know what the fan connection part on the main board for the r7870 is for... connecting aftermarket fans, or more fans combined with the msi stock? :\

I found a solution!
I uninstalled 12.6 beta drivers, restarted my system, installed 12.1 drivers, used search to find atipdl64.dl_ and atipdlxx.dl_, placed them in MSI Afterburner directory, edited MSIAfterburner.cfg to allow unofficial overclocking and voilà! Now it's unlocked to 1170MHz.
For some reason it won't let me change the voltage, but so far it seems like 1100 MHz will work even on stock voltage.

Well, looks like it just so happens that 1050MHz is stable and 1060MHz isn't, so I'm going to have to bump the voltage if I want to reach 1100MHz or even 1150MHz.

Does anyone have an idea how to enable voltage regulation? I already checked "unlock voltage control" and "unlock voltage monitoring" in both user mode and kernel mode. I also tried setting them to "1" in MSIAfterburner.cfg but it didn't help.

Saphire Trixx does have a certain amount of voltagae control but you have to use the slider bar to the right to scrole down to see it as its off the bottom of the view window. I do not have the MSI card (XFX here) but with only a slight voltage increase (1.162 over stock 1.07 on load) I have gone past 1050. Currently at 1210 and have not topped out yet.. I could not get AB to work either but honestly I gave up kind of quick. Never tried GPU Tweak as Trixx is working for me right now. Remove all of the other programs completely and try Trixx again. One thing I have noiced is that the voltage setting in Trixx does not match what GPU-Z reports. When I set Trixx at 1200, GPU-Z reports 1.162 on load. Not sure why.

I tried TriXX and it does have voltage control, but it doesn't seem to do anything with voltage according to GPU-Z. I tried setting it to 1100 mV and 1125 mV, but absolutely nothing happened in GPU-Z. When I ran Unigine Heaven, GPU-Z showed 150 MHz core clock (even though it was set to 1100 MHz) and about 1/3 of FPS I normally get.

Just to be clear, the settings in Trixx will take effect when you load the gpu, not in idle state. Not sure why it works for me and not you but may have something to do with how MSI implemented the voltage regulation. I was actually surprised when my card did respond to the voltage settings change in Trixx.

I have i3-2120 + HD7850..My current driver is 12.3..i tried to install the 12.4 driver and it successfully installed but when i checked the GPU-Z..It still displays the 12.3 driver so i think nothing happen..Then when i played NBA2K12..I encountered hangups so ineed to close the game via task manager then open it again. After several minutes.it happen again..same with other games like Dragon Age 2..BTW i overclock my GPU to 920 and 1250..It didn't happen before i installed the 12.4 driver..what do you think is the problem?thanks guys

Keep in mind that 12.4 drivers will still show up as 12.3 in CCC even after a successful install.
